In most democracies, the supreme arbiter of political conflict is not the parliament, not the president, and certainly not the voters. It is a panel of judges, often appointed for life or near-life terms, whose interpretations of constitutional text can nullify legislation, redraw electoral maps, and determine which rights exist at all. The rise of constitutional courts as the final word on contested political questions represents one of the most significant—and least examined—transformations in modern governance.
The phenomenon accelerated after the Second World War, when framers of new constitutions deliberately sought to insulate certain principles from majoritarian revision. Germany's Basic Law, drafted under Allied supervision, created the Bundesverfassungsgericht precisely because Weimar's parliament had legally dismantled its own democracy. The court was designed to be counter-majoritarian by intention, a guardian against the electorate's worst impulses.
The global spread of judicial supremacy
What began as a post-fascist safeguard became a template. South Africa's 1996 constitution established a Constitutional Court with explicit authority to strike down any law inconsistent with its bill of rights—a direct response to apartheid's legal architecture. Colombia's Corte Constitucional, created in 1991, has intervened in everything from health policy to peace agreements. India's Supreme Court has effectively rewritten constitutional provisions through the "basic structure" doctrine it invented in the 1970s.
The pattern is consistent: countries emerging from authoritarian rule or deep social conflict increasingly vest ultimate authority in courts rather than legislatures. The logic is seductive. If rights are truly fundamental, they should not depend on electoral outcomes. But this logic contains a tension that never resolves.
The legitimacy problem that won't go away
Constitutional courts derive their authority from documents, not mandates. Their members are typically selected through opaque processes involving political horse-trading dressed in the language of legal merit. Once seated, they face no accountability mechanism short of impeachment, which almost never succeeds. They are, by design, insulated from the public they bind.
This creates recurring crises. Poland's ruling party spent years attempting to pack and subordinate its Constitutional Tribunal, arguing that unelected judges were thwarting the democratic will. Hungary's Fidesz government expanded its constitutional court and filled it with loyalists, then used it to entrench illiberal measures. Israel's recent judicial overhaul controversy turned on precisely this question: who guards the guardians?
Defenders of judicial power argue that constitutional courts protect minorities from majorities, rights from politics, and long-term principles from short-term passions. Critics counter that they merely relocate politics into a less transparent arena, where the preferences of a legal elite masquerade as constitutional necessity.
Our take
The honest answer is that constitutional courts are neither the neutral arbiters their defenders claim nor the usurpers their critics allege. They are political institutions exercising political judgment under legal cover—and their power has grown precisely because elected politicians find it convenient to outsource difficult decisions. Abortion, same-sex marriage, campaign finance, climate obligations: these questions get punted to courts because legislators prefer not to own the answers. The courts oblige, and their power expands. Whether this arrangement serves democracy or slowly hollows it out may be the defining constitutional question of our era.
